“…For example, Reference [45] indicates inadequate focus on social embeddedness of mini-grids through stakeholder buy-in. Similar views are also expressed by [13,67]. Sustainability issues of mini-grids have also been raised in the literature-particularly those relying on diesel generation and subsidies [2,66].…”

“…While the cost is likely to decline significantly in the future, the full cost at present remains very high by any standard. Zubi et al confirm that affordability of solar PV remains an issue in regions lacking electricity access but suggest that strategies like high value applications, energy efficient solutions (such as LED lamps) and cost reduction could improve the attractiveness of the technology [67].…”

Abstract:The lack of access to electricity of more than 1.1 billion people around the world remains a major developmental challenge and Goal 7 of the Sustainable Development Goals (SDG) as well as Sustainable Energy for All (SE4ALL) have set a target of universal electrification by 2030. Various studies have identified mini-grid-based electrification as a possible solution. There is a growing body of literature available now that has explored the feasibility, practical application and policy interventions required to support mini-grids. Through a review of available literature, this paper explores whether mini-grids can be a solution for the base of the pyramid (BoP) market and the challenges faced in deploying mini-grids in such markets. Interventions to support the mini-grid deployment are also discussed. The paper finds that the mini-grids are targeting the BoP market but the business is not attractive in profitability terms and requires financial support. Lack of regulatory clarity and non-coordinated policies affect the financial viability of projects, which requires careful support. Mini-grid electrification has hardly been embedded in rural development agenda and hence they have not contributed significantly to livelihood generation. Careful realignment of policies, regulatory frameworks and support systems can better support mini-grid deployment in developing countries.

“…As described in reference [35], the rainflow algorithm is a widely used model [36][37][38][39][40][41][42][43][44][45], usually applied to evaluate battery lifetime when subjected to complex cycles, as in the case of the present investigation. Even if it is not accurate, generally providing an overestimated lifespan evaluation, this strategy was here implemented since the authors were interested in a lifespan comparison among several storage configurations rather than to achieve an absolute estimation of battery useful life.…”

How Hybridization of Energy Storage Technologies Can Provide Additional Flexibility and Competitiveness to Microgrids in the Context of Developing Countries

Hybrid microgrids, integrating renewable energy sources and energy storage, are key in extending energy access in the remote areas of developing countries, in a sustainably way and in providing a good quality of service. Their extensive development faces a financing gap, having a high capital expenditure (CAPEX) also due to high storage costs. In the present work, a case study of a Ugandan microgrid was used to compare various battery technologies employed on their own and in a combination with a flywheel, in terms of their durability and the overall levelized cost of energy (LCOE) of the plant. Simulations show how hybrid storage configurations result in a lower LCOE for the current load profile of the microgrid and even more so for two reference residential and industrial load scenarios, suggesting this would remain the best solution even accounting for future socio-economic development. The resulting LCOE for hybrid storage configurations is lower than the average values reported for microgrid projects and represents a promising solution to speed up the development of such electrification initiatives.

“…However, while PV-system costs have witnessed a decrease globally, the prevailing PV-system cost in Sub Sahara Africa is much higher when compared to the world average and this could be attributed to the political, financial and technological risks (Baurzhan and Jenkins, 2016).. Despite this, in developing countries, PV-systems provide a solution to electricity especially in areas with lack of access to the grid (Zubi et al, 2016). In Tunisia for instance, hybrid renewable energy system applications that entails solar and wind is considered a viable option for meeting high electricity demands (Maatallah et al, 2016).…”

This paper presents a feasibility study of stand-alone solar photovoltaic (PV) systems for the electrification of three residential case study buildings (T4, T5 and T6) in the capital city of Yaoundé, Cameroon. The system was sized taking into account the load of the buildings and the available energy from the sun. The power, area of PV modules and daily energy generated by the PV for T4, T5 and T6 were respectively determined as: 2 103W, 14m 2 and 9.8kWh/day; 3779W, 25.2m 2 and 17.6 kWh/day; and 2 766W, 18.4m 2 and 12.9 kWh/day. The battery bank capacity, size of inverter and controller were respectively obtained as: 40 323Wh, 635W and 93A for T4; 72 433Wh, 795W and 156A for T5; and 53 017Wh, 826W and 114A for T6. The life cycle cost and annualized life cycle cost (ALCC) of the systems were respectively found to be: €15 714 and €1 039 for T4; €27 227and €1 800 for T5; and €20 006 and €1 322 for T6. The average unit electricity cost for T4, T5 and T6 was respectively determined to be €0.52 kW h-1 , €0.50 kW h-1 and €0.51 kW h-1 , higher than the unit cost of residential grid electricity in Cameroon.
